IPC: G01S1/02
Filed: 1966-07-14
Abstract: 1,131,972. Aerials; radio navigation. CSF COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 14 July, 1966 [28 July, 1965], No. 31771/66. Headings H4A and H4D. An aerial system for an I.L.S. localizer transmitter 101 having a modulated carrier output P and a sidebands output B comprises a parabolic cylinder reflector 1 whose axis points along the runway axis 100 and which has a primary aerial 10 at its focus and two primary aerials 11, 12 in its focal plane, said aerials 11, 12 being symmetrically positioned with respect to the aerial 10. The focal distance of the reflector may be 3# (# = wavelength at the mean frequency of the localizer) and its aperture 12#: if the polarizations of the aerials are not the same in the " forward " and " rearward " directions, the focal distance of the reflector must be a whole multiple of #/2. The aerials may be V-shaped with their open ends directed towards the reflector. The aerial 10 is fed with modulated carrier energy, and the aerials 11, 12 are fed in antiphase with sideband energies from terminals 132, 133 of a bridge having three one quarter-wavelength arms a, b, c and one threequarter-wavelength arm d. Modulated carrier energy which is picked up by the aerials 11, 12 passes via the arms b, c of the bridge and a line 14 to a short-circuit 141, from which it is returned for re-radiation. The length of the line 14 is adjusted so that the re-radiated energy combines favourably with that coming directly from the aerial 10. The radiation pattern (Fig. 2, not shown) features a main axially directed lobe of the modulated carrier wave overlapped with antiphased sideband lobes on each side (corresponding respectively to predominances of 90 c/s. and 150 c/s. tones) and a general lower level non-directional coverage on other bearings.

Abstract: 804,791. Winding transfer tails. MACKIE & SONS, Ltd., J. Nov. 15, 1954 [Nov. 17, 1953], No. 31861/53. Class 120(2) In order to wind back from a filled to an empty bobbin mounted in a spinning position a "tag end" of yarn, the lower flange of the empty bobbin has a shoulder on its upper side to catch the yarn during winding back, the yarn being led over a stationary guide so as to be wound below the shoulder. In one embodiment, yarn from a bobbin 18 is wound over a guide 28 and, after being caught by a notch 30 of the rotating bobbin, is wrapped within the space 26 beneath the bobbin formed by the interposition of a washer 24. When the yarn has been severed, the end trailing outwards from the space 26 is caused to strike a stationary post which tightens the turns of yarn round the washer 24. Instead of such a post, pins may be mounted on the bobbin carrier 14 to project into the annular space and prevent wound yarn from being thrown outwardly. The washer 24 may be replaced by a spigot attached either to the bobbin or to the carrier 14. Alternatively, the base of the bobbin may be recessed or grooves may be formed in the base as described in Specification 804,793. The grooves may be so deep as to pass through the peripheral wall of the base.

Title: Process for the preparation of ammonia and oxides of sulphur from ammonium sulphate liquors
IPC: C01B17/50
Filed: 1963-08-14
Abstract: <PICT:1048838/C1/1> In a continuous process for the recovery of ammonia and sulphur oxides from ammonium sulphate liquor, the liquor is introduced in tower 1 into circulating ammonium bisulphate at 300 DEG  C., dehydrated therein, and conveyed to reactor I where it is decomposed to ammonium bisulphate with the liberation via line 4 of half its ammonia content. Ammonium bisulphate equivalent to that formed is led via line 6 to reactor II, the remainder circulating through lines 3 and 5.  In reactor II, ammonium bisulphate reacts with alkali metal sulphate formed on a later stage in a circulating melt of alkali metal pyrosulphate at above 500 DEG  C. to form alkali metal bisulphate and yield the remainder of the ammonia via line 8. The alkali metal bisulphate decomposes to pyrosulphate. In reactor III, pyrosulphate is decomposed at about 900 DEG  C. into sulphate and sulphur trioxide at the rate at which it is formed in reactor II, the remainder recirculating via lines 11a and 11.  The sulphur trioxide may be led off via line 13, washed free of sublimed pyrosulphate in tower 10 and removed via line 12.  Combustion chamber 9 supplies the energy requirements through lines 2, 2a, 2b and 2c. Circulation of the melts is suitably maintained by the pressure of the water vapour and gases formed in the process.  In an alternative process illustrated by Fig. 2 (not shown), ammonium sulphate is converted to ammonium bisulphate and ammonia in reactor I in a melt of alkali metal bisulphate containing alkali metal sulphate, all of the melt is passed to a reactor IIa where the ammonium bisulphate and alkali metal sulphate react to yield the remainder of the ammonia and alkali metal bisulphate. Alkali metal bisulphate at the rate at which it is formed is converted to pyrosulphate in a reactor IIb with evolution of water and decomposed into sulphate and SO3 in a reactor III.  The remainder of the alkali metal bisulphate from reactor IIa takes up the sulphate formed in reactor III and is recycled to the first stage.  In either process the sulphur trioxide formed may be contacted, inside or outside the reactor, with a reducing agent, to increase the yield of sulphur dioxide.  Sulphur trioxide may be removed from the mixed gases by passing through oleum, and the sulphur dioxide taken up in ammonia to form ammonium bisulphite.

Abstract: 342,299. Toothed gearing. HADDAN, R., 31, Bedford Street, Strand, London.- (Aktiebolaget Ljungstroms Angturbin ; 17, 1 Vastra Tradgardsgatan, Stockholm.) Oct. 26, 1929, No. 32612. [Class 80 (i).] In helical toothed gearing wherein gearing on two or more intermediate shafts interconnects aligned driving and driven shafts, the intermediate shafts or the rigidly connected wheels thereon are supported axially by spring and dashpot or frictional damping-means so as to set themselves for even distribution of tooth pressure among the parallel driving-routes and to avoid shock due to tooth irregularities. A motor 1, Fig. 1, drives, through a flexible shaft 3, a helical pinion 5 gearing with wheels 6, 7 &c. on intermediate shafts 8, 9 carrying helical pinions 10, 11 &c. engaging a wheel 12 on the driven shaft 13. The gearing is so arranged as to produce a small resultant axial pressure on the shafts 8, 9, which slide in bearings against springs 19, 20 in chambers which contain oil acting to produce a dashpot damping- effect. The extension 8a of the shaft 8, Fig. 4, carries on thrust bearings a piston 22 supported between springs 19, 20 in oil-containing chambers between which the oil is forced by leakage during axial movement of the shaft, which slides in a roller bearing 16. In a modification, springs are arranged between a central partition in the casing and the inner sides of a double piston moving with the shaft 8, oil being forced through holes in the partition. In the two latter constructions, the axial control means need be provided only at one end of each shaft. As shown in Fig. 2, the shaft 8 engages at each end by a Michell bearing 18 a piston 22 supported by springs 20 which resiliently and frictionally control the axial movement of the shaft, no oil being used. The wheels 6, 10 &c. may be axially movable together upon the shaft 8 while turning therewith, damping being effected by the frictional engagement of the wheels with the shaft.

The gate 7 is isolated during at least a part of the clock cycle to retain the boosted level. An input at 9 is double inverted in # 3  time by F.E.T.'s 28, 29, 37, 40, 41 and applied to F.E.T. 4 gate, the inverted signal at 35 being applied to a F.E.T. 53 to earth the output when the F.E.T. 4 is off. In # 3  time, when F.E.T. 29 conducts to turn on F.E.T. 4, provided F.E.T. 28 is off depending upon the input 9, a F.E.T. 16 in the boost circuit conducts to apply - V to C21 whose right hand plate 20 is earthed to # 4  by F.E.T. 17 which is also turned on by - V applied through F.E.T. 16. C22 is also charged to -V (# v ) in # 3  time by F.E.T. 15. In # 4  time, point 20 goes to - V and points 58, 11 are therefore carried even further negative so that F.E.T. 17 is turned on even harder to hold point 20 at - V; and F.E.T. 10 conducts to make the gate of F.E.T. 4 more negative than - V so that the threshold drop across F.E.T. 4 disappears. After # 4  (e.g. during # 1 , # 2 ) F.E.T. 10 is off to isolate F.E.T. 4 gate, since point 20 goes back to earth. The charge on F.E.T. 4 gate is refreshed each cycle until the input 9 changes.
